Spinoffs happen fairly often in movies and TV, and we see them from time to time in videogames, too. Usually they're forgettable, but sometimes you'll see a spinoff that's so weird that you just have to check it out. They're a lot more rare these days than they used to be, mostly because to the higher cost (and risk) of game development, but they still pop up from time to time. These eight games prove that you can make a weird spinoff to just about anything.
Uncharted: Fight for Fortune
After playing all three of the Uncharted games, I think everyone was ready for a card game based on the series, right? NO? OK then. That's exactly what Uncharted: Fight for Fortune was - a Vita title that translated the world of the games into a Magic: the Gathering-like experience. Some of the best cards came from syncing trophies earned in the other Uncharted games. It wasn't a bad game, just a really odd one.
